I can only state that linux_mprotect dont called with addr at 0x50000000. Nov 4 12:40:14 tiger kernel: mprotect: addr:55c00000, len:4096, prot:1, bsdprot:5, ret:0 Nov 4 12:40:14 tiger kernel: mprotect: addr:55c81000, len:4096, prot:1, bsdprot:5, ret:0 This are only addresses which are arguments for linux_mprotect. I have suspected linux_mmap_common but it not called either. Thanks. Valery.
